Description

[Detailed Description of the Invention] The present invention is a jacket for storing recording and reproducing discs used in recording and reproducing devices such as disc sheet recorders and video disc devices, and is particularly suitable for storing discs having a hole in the center. This is about the best jacket for.

As is well known, in video disks and the like that have high-density magnetic recording, if lumps adhere to them or if they are touched directly by hand, this can cause dropouts and blocking, causing serious problems.

Therefore, when storing or handling this type of video disc, etc., it is necessary to avoid as much as possible the above-mentioned dust adhesion and direct contact with hands.

This invention is used in disc sheet recorders, video disc devices, etc., when in use, the recording/playback disc is mounted in a predetermined position through a jacket, and then automatically pulled out from inside the jacket and set on a turntable etc. By using this device with a recording/playback device that automatically pulls the playback disc back into the jacket and then removes it using the jacket, it ensures that dust does not adhere to the playback disc or that it is touched directly by hand. This disc storage disc is capable of reliably preventing the recording/playback disc from accidentally falling out of the jacket, especially when the disc is removed from the recording/playback device. It is an object of the present invention to provide a disc storage disc that is extremely simple in structure and manufacture.

Embodiments of the present invention will be described below based on the drawings.

First, in Figures 1 to 3, 1 is the top panel;
2 is a lower panel, 3 is a frame body, and these panels 1,
2 and the frame 3 are molded from paper or plastic.

Note that the frame body 3 has no S-shape, and the inner peripheral surface 3a has an S-shape.
゛It is formed in a semicircular arc shape.

Both panels 1 and 2 are superimposed on the upper and lower sides of the frame 3, and the three peripheral edges 1at2a of both panels 1 and 2 are overlapped at the frame 3 portion.
The jacket 4 is constructed by joining them together by adhesion, heating, or the like.

Therefore, this jacket 4 is provided with an oblong opening 5 in a part of its curved surface, and a disc storage space 6 with a height corresponding to the thickness of the frame 3 is provided inside.

The disc 7 for recording and reproducing, such as a video disc, is inserted into the space 6 through the opening 5 and stored therein.

Incidentally, the disk 7 is provided with a circular hole 8 in its center.

On the other hand, the jacket 4 is provided with a pair of convex portions 9, 10 on some of the panels 1, 2 at the central portion S of the space 6, which protrude into the space 6.

In this case, the tip 10a of one of the protrusions 10 is inserted into the insertion hole 11 provided in the tip 9a of the other protrusion 9.

One of the protrusions 10 is inserted into a hole 8 of the disk 7 housed in the space 6.

Note that a hole 12 is also provided at the tip 10a of one of the protrusions 10.

Furthermore, the relationship between the height h of the protrusion 10 and the thickness d of the jacket 4 is configured such that d≧h, but this is because when the jackets 4 are stacked, the protrusion 10 is pushed and This is to eliminate inconveniences such as slippage.

According to the jacket 4 configured as described above, one convex portion 10 of the jacket 4 is inserted into the hole 8 of the disk 7,
In addition, since the tip 10a of one of the convex portions 10 is inserted into the insertion hole 11 of the tip 9a of the other convex portion 9, the disk 7 housed in the internal space 6 is released from the opening 5 to the outside of the jacket 4. There is no chance of it falling off unexpectedly.

In addition, when pulling out the disk 7 from the opening 5, it is sufficient to pull the convex portion 10 downward as shown by the imaginary line in FIG.

Incidentally, FIG. 4 is a diagram illustrating an example of a method for attaching and detaching the disk 7 to and from a recording/reproducing apparatus such as a disk sheet recorder or a video disk apparatus.

That is, first, the disk 7 is mounted in a predetermined position using the jacket 4.

Next, the convex portion 10 of the jacket 4 is automatically pulled downward, and the disc is moved by one or more rollers 17 for inserting and ejecting the disc inserted into one or more roller insertion holes 16 provided in the top panel 1. 7 is automatically pulled out from the opening 5 of the jacket 4.

This disk 7 is then completely pulled out from inside the jacket 4 by one or more relay rollers 18 and automatically set on a turntable 19 or the like.

Next, after recording or reproduction, the disc 7 is first pulled back from the top of the turntable 19 toward the jacket 4 by the roller 18, and then completely pulled back into the jacket 4 by the roller 17.

Thereafter, the convex portion 10 of the jacket 4 is inserted into the hole 8 of the disc 7, and the disc 7 is removed from the recording/reproducing apparatus using the jacket 4.

In addition, in this recording/reproducing device, the convex portion 10 of the jacket 4
There are various ways to lower the
As shown in the figure and FIG. 6, the convex portion 1 of the jacket 4
The locking means 20 is locked in the hole 12 of 0.
There is a method in which the convex portion 10 is pulled down depending on the situation.

However, in this case, as shown in FIG. 5, the tip 20a of the locking means 20 is inserted into the hole 12 from below in a state in which it is reduced to a diameter smaller than the diameter of the hole 12, and then, as shown in FIG. It is necessary to take measures such as enlarging it, hooking the protrusion 10 with its tip 20a, and pulling it down.

As described above, the present invention involves joining the peripheral edges of a pair of upper and lower panels to each other with a horizontally elongated opening in part to form a disc storage space inside. A pair of protrusions protruding into the space is provided in the panel, and the tip of one protrusion is inserted into an insertion hole provided at the tip of the other protrusion, and a hole is provided in the center. Since the disc storage jacket is configured such that a recording/reproducing disc is housed in the space and one of the protrusions is inserted through the hole in the center of the jacket, it is possible to store a recording/reproducing disc with a hole in the center. It can be stored inside a jacket and securely locked inside the jacket.

Therefore, it is possible to reliably prevent the disc from accidentally falling out of the opening of the jacket and being damaged, and it is possible to reliably protect the disc.

However, the structure is very simple, as the purpose can be achieved by inserting a pair of protrusions provided on a pair of panels of the jacket into each other, and by inserting one protrusion into a hole in the disc. It is also easy to manufacture and very low cost.
